The datacenter I am looking to Colo with is being very stingy about IP addresses, only giving me 8 for a quarter rack. I need like 40 and am planning to need a lot more. I saw on the Arin site that I could get about 4k ipv4 for about $1250, is that a total cost or is that annually. Also once I have the IP address allocation what do I do with it, i hear i need a bgp router, would the data center have one, is this something I would need? Any help would be great, thanks!
ARIN is pretty strict about their allocations, especially in recent years. Unless you can demonstrate a need for a /20 or a /22 they all but require you to get your addresses from an upstream provider. You might have an easier time buying additional IPs from your hosting provider. If they won't or can't give you additional addresses then that's probably a good indication that you should look for a different provider.
